Abstract

Process for dihydroxy benzenes from hydroxybenzenes opt. substd. by 1-12C alkyl; and also for monoethers of dihydroxybenzenes from 1-12C alkyl or aryl phenolethers. The process is carried out, pref. at 50-100 degrees C, in the presence of one of: peracid stabilisers; N-contg. polycarboxylic acids able to chelate a heavy metal together with their Mg, Na, K salts; hydroxy polycarboxylic acids able to chelate with a heavy metal together with their Mg, Na salts; Na or K slats of phosphonic acid mono- or di-lower alkyl ethers; Na salt of pyrophosphoric acid mono-, di- or tri-lower alkyl ethers. Specif. using 2:6 di(hydroxymethyl)pyridine, 8-hydroxyquinoline, dioctyl dihydrogen pyraphosphates and pyrophosphates of formula H5R'5(P3O10)2 or Na5R'5(P3O10)2, where R' is 4-10C alkyl. Pref. peracids are peracetic, perpropionic or perisobutyric used at 0.1-0.5 mol/mol phenol. The catalyst is pref. 0.05-1% of the phenol wt. Process results in improved yields.
